About this cartoon: The Republican "birther" movement has continually demanded that Obama "Show us the birth certificate!" -- which the president has done, despite the fact that no president ever having had to do so. But his Republican challenger has consistently refused to publicly show his income tax returns for more than the two most recent years, despite the fact that every presidential candidate for many years has been expected to do just that.
